Overview

Moxa UC-3100 Series computers can be used as edge-field smart gateways for data pre-processing and

transmission, as well as for other embedded data acquisition applications. The UC-3100 Series includes

three models, each supporting different wireless options and protocols.

The UC-3100’s advanced heat dissipation design makes it suitable for use in temperatures ranging from -30

to 70°C. In fact, the Wi-Fi and LTE connections can be used simultaneously in both cold and hot

environments, allowing you to maximize your “data pre-processing” and “data transmission” capability in

most harsh environments.

Reset to Factory Default

For details on resetting your device to factory default values, refer to the Function Button and LED

Indicators section.

ATTENTION

Reset to D

efault will erase all the data stored on the boot storage

Please back up your files before resetting the system to

the factory default configuration. All the data

stored in the

UC-3100‘s boot storage will be erased when it is reset to the factory default configuration.

Real-time Clock

The real-time clock in the UC-3100 is powered by a lithium battery. We strongly recommend that you do not

replace the lithium battery without the help of a Moxa support engineer. If you need to change the battery,

contact the Moxa RMA service team.

WARNING

There is a risk of explosion if the battery is replaced

with an incorrect battery type.

Placement Options

The UC-3100 computer can be mounted on to a DIN rail or on a wall. The DIN-rail mounting kit is attached by

default. To order a wall-mounting kit, contact a Moxa sales representative.

DIN-rail Mounting

To mount the UC-3100 on to a DIN rail, do the following:

1. Pull down the slider of the DIN-rail bracket located at the back of the unit

2. Insert the top of the DIN rail into the slot just below the upper hook of the DIN-rail bracket.

3. Latch the unit firmly on to the DIN rail as shown in the illustrations below.

4. Once the computer is mounted properly, you will hear a click and the slider will rebound back into place

automatically.

Wall Mounting (optional)

The UC-3100 can also be wall mounted. The wall-mounting kit needs to be purchased separately. Refer to

datasheet for more information.

1. Fasten the wall-mounting kit to the UC-3100 as shown below:

2. Use two screws to mount the UC-3100 on to a wall.

ATTENTION

The wall

-mounting kit is not included in the package and must be purchased separately.

Wiring Requirements

In this section, we describe how to connect various devices to the embedded computer. You must pay

attention to the following common safety precautions, before proceeding with the installation of any

electronic device:

• Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must

cross, make sure the wires are perpendicular at the intersection point.

NOTE: Do not run the wires for signal or communication and power wiring in the same wire conduit. To

avoid interference, wires with different signal characteristics should be routed separately.

• You can use the type of signal transmitted through a wire to determine which wires should be kept

separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled

together.

• Keep input wiring and output wiring separate.

• We strongly advise that you label wiring to all devices in the system for easy identification.

ATTENTION

Safety First!

Be sure to disconnect the

power cord before installing and/or wiring the computer.

Electrical Current

Caution!

Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes

dictating the maximum current allowable for each wire size.

If the

current goes above the maximum ratings, the wiring could overheat, causing serious damage to

your equipment.

Temperature Caution!

careful when handling the unit. When the unit is plugged in, the internal components generate heat,

and consequently the

outer casing may be hot to touch by hand.

Connector Description

Power Connector

Connect the power jack (in the package) to the UC-3100’s DC terminal block (located on the bottom panel),

and then connect the power adapter. It takes several seconds for the system to boot up. Once the system is

ready, the SYS LED will light up.

Grounding the UC-3100

Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). There

are two ways to connect the UC-3100 grounding wire to the ground.

1.Through the SG (Shielded Ground, sometimes called

Protected Ground):

The SG contact is the left

-most contact in the 3-pin power

terminal block connector when viewed from the angle shown

here. When you connect to the SG cont

act, the noise will be

routed through the PCB and the PCB copper pillar to the metal

chassis.

UC-3100 Series Hardware UM Hardware Connection Description

2. Through the GS (Grounding Screw):

The GS is located between the console port and the power

connector. When you connect to the GS wire, the noise is routed

irectly from the metal chassis.

SIM Card Socket

The UC-3100 comes with two nano-SIM card sockets for cellular communication. The nano-SIM card sockets

are located on the same side as the antenna panel. To install the cards, remove the screw and the

protection cover to access the sockets, and then insert the nano-SIM cards into the sockets directly. You will

hear a click when the cards are in place. The left socket is for SIM 1 and the right socket is for SIM 2. To

remove the cards, push the cards in before releasing them.

RF Connectors

The UC-3100 comes with RF connectors to the following interfaces.

Wi-Fi

The UC-3100 comes with a built-in Wi-Fi module (UC-3111 and UC-3121 only). You must connect the

antenna to the RP-SMA connector before you can use the Wi-Fi function. The W1 and W2 connectors are

interfaces to the Wi-Fi module.

Bluetooth

The UC-3100 comes with a built-in Bluetooth module (UC-3111 and UC-3121 US region only). You must

connect the antenna to the RP-SMA connector before you can use the Bluetooth function. The W1 connector

is the interface to the Bluetooth module.

Cellular

The UC-3100 comes with a built-in cellular module. You must connect the antenna to the SMA connector

before you can use the cellular function. The C1 and C2 connectors are interfaces to the cellular module.

For additional details refer to the UC-3100 datasheet.

SD Card Socket (UC-3111 and UC-3121 US only)

The UC-3111 comes with a SD-card socket for storage expansion. The SD card socket is located next to the

Ethernet port. To install the SD card, remove the screw and the protection cover to access the socket, and

then insert the SD card into the socket. You will hear a click when the card is in place. To remove the card,

push the card in before releasing it.
